According to the pesticide composition containing isoproturon, flucarbazone and diflufenican, a synergistic effect is exerted within a certain proportion range, the prevention and control effect of the composition is obviously improved compared with a single component, the pesticide dosage is reduced, the pesticide use frequency is decreased, the pesticide cost is reduced, the negative influence of pesticide on ecological environment is reduced, and keeping of ecological balance is facilitated.
Description
Technical field
The present invention relates to technical field of pesticide, particularly relating to a kind of composition pesticide containing isoproturon, flucarbazone and diflufenican for preventing and kill off cornfield gramineae weed, broad leaved weed.
Background technology
Wheat weeds harm directly affects the production of wheat crops, is the key factor of restriction crop yield.Prevent and kill off the vital task that wheatland crop smothering is development Wheat Production.The use of chemical herbicide is one of important symbol of agricultural modernization.Current wheat weeds is prevented and kill off mainly based on aryloxyphenoxypropanoates class weed killer herbicide cauline leaf spraying after weeds seedling.Although have multiple weed killer herbicide kind available for different phase, most of kind is difficult to ensure a drug and keep crop interior without grass for whole breeding time.Therefore from economy, environmental angle, grope to probe into wheat paddock and once use and keep seeming particularly urgent without the safety of grass, highy potent herbicide in crop whole breeding time.
Isoproturon, chemical name: 3-(4-isopropyl phenyl)-1,1-dimethyl urea or-3-are to cumenyl-1,1-dimethyl urea.Belong to phenyl ureagroup herbicides, absorb inhibited photosynthesis electron transmission mainly through root and cauline leaf, for before selectivity seedling, herbicide after seedling, also there is selection systemic action; Isoproturon is efficient, broad-spectrum herbicide, can be applicable to the crop Tanakas such as wheat, corn, paddy rice and prevents and kill off grass family and broad leaved weed.
Diflufenican, chemical name: 2 ', 4 '-two fluoro-2-(between a, a, a-trifluoro methylphenoxy)-3-pyridine anilide.Belong to acetamide-group herbicides, by weeds young shoot and Root Absorption, conduct in plant body, suppress herxheimer-liked reaction, thus cause weeds young shoot decolour or bleach.Diflufenican effectively can prevent and kill off barley, wheat, the grassy weed of paddy field and broad leaved weed.
Summary of the invention
Object of the present invention: solve existing weed killer herbicide to farmland weed develop immunity to drugs problem, single use control efficiency poor, once use the problem being difficult to effectively to control Weed infestation in wheat whole breeding time, the object of this invention is to provide a kind of composition pesticide containing isoproturon, flucarbazone and diflufenican, make it have efficient, wide spectrum, environmentally friendly, be beneficial to the features such as the wheat weeds comprehensive regulation.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of composition pesticide containing isoproturon, flucarbazone and diflufenican, comprise active component and auxiliary element, described active component is isoproturon, flucarbazone and diflufenican, and the mass ratio of isoproturon, flucarbazone and diflufenican is 1:1.2-1.8:1-2; Described isoproturon, flucarbazone and the diflufenican mass percentage accounted in composition is 5-80%; Described auxiliary element comprises at least one in dispersant, emulsifier, wetting agent, binding agent, antifreezing agent, thickener.
Further, the mass ratio of described isoproturon, flucarbazone and diflufenican is 1:1.5:1.6.
Further, described isoproturon, flucarbazone and diflufenican account for the mass percentage in composition is 20-80%.
Further, described dispersant is the mixture of naphthalene sulfonate of alkylphenol polyoxyethylene, alkylphenol-polyethenoxy base ether formaldehyde condensation products and modification, and its mass ratio is 1:1.2-1.6:1.5-3.
Further, described emulsifier is the mixture of two phenethyl phenol polyethenoxy ether, phenethyl phenol polyethenoxy ether 600# and polyoxyethylene sorbitan fatty acid ester, and its mass ratio is 1:0.8:1.2.
Further, described antifreezing agent is the mixture of dimethyl sulfoxide (DMSO), urea and thiocarbamide, and its mass ratio is 0.3:1:0.5.
Further, the formulation of described composition pesticide is wetting powder, water dispersible granules, suspending agent, microemulsion, finish, suspension emulsion, missible oil, aqueous emulsion or oil-suspending agent.
The application of a kind of composition pesticide containing isoproturon, flucarbazone and diflufenican in control cornfield gramineae weed, broad leaved weed.
Further, when preventing and treating cornfield gramineae weed, broad leaved weed, used before 3 leaf phases before broadcasting rear seedling or after broadcasting.
Flucarbazone, chemical name is 1H-1,2,4-triazole-1-carbamyl-4,5-2H-3-methoxyl group-4-methyl-5-O-N-[[2-(trifluoro methoxy) benzene] sulphonyl]-sodium salt.Belong to sulfonylurea internal-suction type efficient wheat field herbicidal, can be absorbed by the root of weeds and cauline leaf, by suppressing the activity of acetolactate synthestase in weeds body, destroying the normal Physiological and Biochemical Metabolism of weeds and playing activity of weeding.Effectively can prevent and kill off wheat paddock major part grassy weed, simultaneously also can effective control section broad leaved weed.It can very fast metabolism in wheat body, has fabulous safety to wheat.
The invention has the beneficial effects as follows: compared with existing product, the composition pesticide containing isoproturon, flucarbazone and diflufenican of the present invention, tool has the following advantages:
1) composition pesticide containing isoproturon, flucarbazone and diflufenican of the present invention, synergistic effect is shown in certain ratio range, the control efficiency of composition is significantly improved than single dose, reduce the using dosage of agricultural chemicals, decrease Pesticide use number of times, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope, be conducive to keeping ecological balance.
2) composition pesticide containing isoproturon, flucarbazone and diflufenican of the present invention, the combination of three kinds of active ingredients, expands herbicide spectrum, not only seals but also kill, a drug effectively can control Weed infestation in wheat whole breeding time, can make up single dose familiar lacunas and limitation.
3) composition pesticide containing isoproturon, flucarbazone and diflufenican of the present invention, active ingredient mechanism of action is different, the shortcoming that long-term certain product of single use easily produces resistance can be overcome, extend the service life of medicament, the Weed Resistance comprehensive regulation is of great importance.
4) composition pesticide containing isoproturon, flucarbazone and diflufenican of the present invention, the lasting period is long, not only seals but also kill, easy to use, and saving of work and time is fool proof to wheat, is easy to peasant and grasps.
